DOWN-:DROP SIGHT-FEED LUBRIGATOR.

Specicatcn of Letters Patent.

Application le. November 12, 1915. Serial No. 61,036.

To all whom t may concern:

Be it known that I, HnRwAN W. S'rnnonnn, a citizen of the United States of America, and resident of St. Louis, Missouri, have invented certain new and Useful Improvements in Down-Drop Sight-Feed Lubricators, of which the following is a specification.

This invention relates to improvements in a drop sight feed lubricator and has for its object a receptacle connected to a lead attached to an engine or other parts to be lubricated, an oil supply pipe and a steam connection by which the steam is admitted into the receptacle for properly thinning a heavy oil which is permitted to pass down to the lead.

A further object of my invention is to construct a lubricator to handle a comparatively heavy oil which is properly thinned by the steam fed to the engine, permitting the oil to drop downward past a sight opening so that the oil supply can be readily observed and then regulated.

Figure 1 is a side elevation of my complete invention with a part thereof in section.

Fig. 2 is a horizontal section of the same taken on the line 2-2 of Fig. l.

In the construction of my invention I provide a receptacle preferably in the form of a cylinder 3, having a conical bottom 4, and to which is connected a valve 5, controlling the passage and supply of steam to the engine or parts to be lubricated through the pipe 6.

Leading in the upper portion of the cylinder is a steam pipe 7 through which steam is admitted from the steam supply, and in said upper portion is connected an oil supply pipe 8, to which is attached a valve 9, by which the flow of oil is regulated.

The cylinder is also provided with a sight opening 10, provided with a glass or other transparentV cover 11, through which the drops of oilmay be observed as they travel down from the inlet of the pipe 8, to the conical bottom 4.

The position of the pipe 8, and valve 9, may be differently located depending upon the space and location of the cylinder, for

instance, the pipe may branch off horizontally depending upon the location of the oil supply tank.

The essential feature of my invention is to equip a lubricator by which oil preferably of a heavy nature can be utilized, reduced to an easy flowing consistency by the steam and permitted to drop downward instead of oating upward as done heretofore, and to observe the passage of the oil by means of a sight opening in proper line therewith.

The device is simple in construction but has merit which no other lubricators possess in the handling of a comparatively heavy oil to be used for lubricating purposes.

I-Iaving fully described my invention, what I claim, is:

l. A lubricator for supplying heated oil to steam engine cylinders comprising a cylindrical steam chamber having a flat top and a conical bottom, a steam inlet at the top of said chamber, a valve governed oil inlet in the top of the steam chamber to allow the oil to drip therein, an opening formed in the steam'chamber for observing the rate of iiow of oil, and a valve governed outlet attached to the conical body of the lubricator for regulating the flow of oil to the cylinders, substantially as specified.

2. A lubricator for supplying steam heated oil to steam engine cylinders and the like, comprising a cylindrical steam chamber having a flat top and a truncated cone shaped bottom, a dry steam inlet at the top of said chamber, a valve controlled oil inlet for allowing a vheavy oil to drip slowly therethrough in the top of the dry steam chamber, transparent opening formed in the dry steam chamber for observing the rate of dripof oil, and a valve governed outlet attached to the bottom of the lubricator'for regulating the flow of heated oil to the cylinder under steam pressure, substantially as specified.

3. A lubricator for supplying heated oil to steam engine cylinders by means of live steam pressure comprising a cylindrical steam chamber having a flat top and a coni cal bottom, a steam inlet at the top of said steam chamber, a valve controlled inlet for allowing a heavy oil to slowly percolate `In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.
